I have a brand new, never used Orion TOAG (see:
http://www.bintel.com.au/Astrophotog...oductview.aspx). I have decided to keep using the Takahashi guidescope I modified instead for my guiding needs.
I am either selling it for $130, or will trade directly for a set of 90mm guide rings with base the same as the Losmandy here:

MUST be 90mm guiderings (or slightly LESS - not more than 90mm though) with the base clamps.
